Description

Spreizanker aus Metall Expansion anchors made of metal
Die Erfindung betrifft einen Spreizanker aus Metall mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to an expansion anchor made of metal with the features of the preamble of claim 1.
Zur Befestigung von Gegenständen an einem Untergrund ist häufig gefordert, dass der verwendete Spreizanker sowohl eine hohe Auszugsfestigkeit aufweist als auch die Verwendung von Schrauben oder Gewindestangen erlaubt. Hierzu sind Spreizanker aus Metall mit einem Innengewinde erforderlich. Weiterhin verlangt die Verankerung in der Zugzone, in der üblicherweise Risse auftreten, dass der Spreizanker ein Nachspreizverhalten aufweist. Da die allgemein als Schlaganker bekannten Spreizanker nicht nachspreizen können, schlägt die Druckschrift EP 0 995 914 A2 einen Spreizanker vor, dessen Ankergrundteil ein Innengewinde und einen Spreizabschnitt aufweist, auf den eine Spreizhülse axial verschiebbar aufgesetzt ist. Der Spreizanker wird durch Einziehen des Ankergrundteils in die Spreizhülse verankert, wobei die Spreizhülse radial im Bohrloch verspannt wird, ohne axial verschoben zu werden. Weiterhin schlägt die Druckschrift vor, dass der Spreizanker vormontiert eine Schraube mit einem aufgesetzten hülsenartigen Stauchelement aufweist. Die Schraube ist soweit in das Innengewinde des Ankergrundteils eingeschraubt, dass das Stauchelement auf der einen Seite am Schraubenkopf und auf der anderen Seite an der der Schraube zugewandten Stirnseite des Ankergrundteils anliegt. Das Stauchelement gewährleistet beim Einbringen des Spreizankers in das Bohrloch, dass zwischen dem Ankergrundteil und dem Schraubenkopf eine hinreichend große Distanz gegeben ist, so dass das Ankergrundteil ausreichend in die Spreizhülse eingezogen werden kann, ohne vorher am Schraubenkopf aufzusitzen. Bei diesem Vorgang wird das Stauchelement axial gestaucht.To fasten objects to a surface, it is often required that the expansion anchor used not only has a high pull-out strength but also allows the use of screws or threaded rods. This requires expansion anchors made of metal with an internal thread. Furthermore, the anchoring in the tension zone, in which cracks usually occur, requires that the expansion anchor has a post-expansion behavior. Since the expansion anchors, which are generally known as impact anchors, cannot expand, the document EP 0 995 914 A2 proposes an expansion anchor whose base part has an internal thread and an expansion section onto which an expansion sleeve is axially displaceably placed. The expansion anchor is anchored by pulling the base part of the anchor into the expansion sleeve, the expansion sleeve being braced radially in the borehole without being axially displaced. Furthermore, the publication suggests that the expansion anchor has a screw with a sleeve-like compression element attached, pre-assembled. The screw is screwed into the internal thread of the anchor base part to such an extent that the compression element rests on one side against the screw head and on the other side against the end face of the anchor base part facing the screw. When inserting the expansion anchor into the borehole, the compression element ensures that there is a sufficient distance between the anchor base part and the screw head, so that the anchor base part can be sufficiently drawn into the expansion sleeve without first sitting on the screw head. In this process, the compression element is compressed axially.
Der Nachteil einer solchen Anordnung ist, dass das Stauchelement nur in Verbindung mit einer vormontierten Schraube zur Verwendung kommen kann. Wird dagegen eine besonders lange Schraube oder eine Gewindestange zur Befestigung benötigt, da beispielsweise ein besonders großes Bauteil befestigt werden soll oder der Anker zum Abhängen von Rohren an einer Decke benutzt werden soll, ist die vormontierte Schraube mit Stauchelement ungeeignet.The disadvantage of such an arrangement is that the compression element can only be used in connection with a pre-assembled screw. If, on the other hand, a particularly long screw or a threaded rod is required for fastening, since For example, if a particularly large component is to be attached or the anchor is to be used to hang pipes from a ceiling, the pre-assembled screw with compression element is unsuitable.
Der Erfindung liegt daher die Aufgabe zu Grunde, einen nachspreizenden Spreizanker aus Metall mit Innengewinde zu schaffen, der für unterschiedlich lange Schrauben, Gewindestangen oder dgl. geeignet ist.The invention is therefore based on the object of creating a spreading anchor made of metal with an internal thread, which is suitable for screws, threaded rods or the like of different lengths.
Die Aufgabe wird erfindungsgemäß durch den Spreizanker mit den Merkmalen des Anspruchs 1 gelöst. Der erfindungsgemäße Spreizanker weist ein Stauchelement auf, das im Ankergrundteil angeordnet ist. Hierdurch kann der Spreizanker mit unterschiedlich langen Schrauben gesetzt werden, beispielsweise um unterschiedlich große Gegenstände zu befestigen. Die Schraube wird soweit in das Innengewinde des Spreizankers eingeschraubt, bis es mit seinem Einführende auf dem Stauchelement aufsitzt. Dieses sitzt wiederum mit seinem anderen Ende auf dem Grund der Bohrung für das Innengewinde, einem entsprechenden Absatz oder dgl. auf. Hierdurch verspürt der Bediener einen deutlichen Anstieg des Eindrehmoments, der signalisiert, dass der Spreizanker in diesem Zustand in das Bohrloch im Untergrund eingebracht werden kann. Der Spreizanker wird soweit eingeschoben, bis die Schraube mit ihrem Kopf auf dem Untergrund bzw. einer dazwischen liegenden Unterlegscheibe und/oder dem zu befestigenden Bauteil aufsitzt. Zum Verspreizen des Spreizankers wird die Schraube weiter in das Innengewinde geschraubt. Da der Schraubenkopf als Widerlager wirkt, wird das Ankergrundteil entgegen der Einbringrichtung gezogen und hierdurch die feststehende Spreizhülse gespreizt. Gleichzeitig wird das Stauchelement gestaucht. Gegenüber dem ersten Eindrehen der Schraube verläuft dieser Vorgang auf einem höheren Drehmomentniveau und daher unter Zuhilfenahme von Werkzeug. Dabei muss die Stauchfähigkeit des Stauchelements derart bestimmt sein, dass sich durch die Stauchung während des Spreizvorgangs kein erneuter, signifikanter Drehmomentanstieg ergibt, solange eine hinreichenden Verspreizung der Spreizhülse noch nicht erreicht ist. Der erneute Drehmomentanstieg soll also durch die Verspreizung der Spreizhülse und nicht etwa durch die Stauchung des Stauchelements erfolgen. Nach erfolgter Verspreizung kann die Schraube entweder im Spreizanker verbleiben, wenn sie die Befestigungsaufgabe bereits erfüllt, oder sie wird wieder herausgeschraubt und statt dessen beispielsweise eine Gewindestange eingeschraubt. In diesem Fall ist die Schraube lediglich als Setzwerkzeug zu verstehen. Vorzugsweise ist das Stauchelement eine Kunststoffbuchse. Dies ermöglicht eine einfache Herstellung durch Ablängung von einem Rohr. Daneben sind aber auch andere Materialien und Formen denkbar, wie beispielsweise eine Druckfeder aus Stahl. Das Stauchelement ist außerdem vorzugsweise verliersicher im Ankerteil angeordnet, beispielsweise dadurch, dass es mit Presssitz gefügt oder in das Innengewinde des Ankerteils eingeschraubt ist. Hierdurch kann das Stauchelement nicht bei der Lagerung, dem Transport oder bei der Über-Kopf-Montage verloren gehen.The object is achieved by the expansion anchor with the features of claim 1. The expansion anchor according to the invention has a compression element which is arranged in the base part of the anchor. As a result, the expansion anchor can be set with screws of different lengths, for example to fasten objects of different sizes. The screw is screwed into the internal thread of the expansion anchor until it is seated on the compression element with its insert. This in turn sits with its other end on the bottom of the bore for the internal thread, a corresponding paragraph or the like. As a result, the operator feels a significant increase in the screwing torque, which signals that the expansion anchor can be inserted into the borehole in the subsurface in this state. The expansion anchor is pushed in until the screw rests with its head on the surface or an intermediate washer and / or the component to be fastened. To expand the expansion anchor, the screw is screwed further into the internal thread. Since the screw head acts as an abutment, the base part of the anchor is pulled against the direction of insertion, thereby spreading the fixed expansion sleeve. At the same time, the compression element is compressed. Compared to the first screwing in of the screw, this process takes place at a higher torque level and therefore with the help of tools. The compressibility of the compression element must be determined in such a way that there is no renewed, significant increase in torque due to the compression during the expansion process, as long as sufficient expansion of the expansion sleeve has not yet been achieved. The renewed increase in torque should therefore occur through the expansion of the expansion sleeve and not through the compression of the compression element. After expansion, the screw can either remain in the expansion anchor if it already fulfills the fastening task, or it is unscrewed again and, for example, a threaded rod is screwed in instead. In this case, the screw is only to be understood as a setting tool. The compression element is preferably a plastic bushing. This enables simple manufacture by cutting to length from a tube. In addition, other materials and shapes are also conceivable, such as a steel compression spring. The compression element is also preferably arranged so that it cannot be lost, for example by being press-fitted or screwed into the internal thread of the anchor part. As a result, the compression element cannot be lost during storage, transportation or overhead installation.
Die Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Figur 1 zeigt den erfindungsgemäßen Spreizanker 1 zur Befestigung des Bauteils 2 an dem Untergrund 3 im Zustand vor der Verspreizung. Der Spreizanker 1 ist aus Stahl und weist ein Ankergrundteil 4 mit einem Innengewinde 5 auf. Das Ankergrundteil 4 weist einen im Durchmesser reduzierten, sich entgegen der Einbringrichtung des Spreizankers 1 verjüngenden Spreizabschnitt 6 auf, auf den eineThe invention is explained in more detail below with reference to an embodiment shown in the drawing. FIG. 1 shows the expansion anchor 1 according to the invention for fastening the component 2 to the base 3 in the state before the expansion. The expansion anchor 1 is made of steel and has an anchor base part 4 with an internal thread 5. The anchor base 4 has a reduced diameter, tapering against the direction of insertion of the expansion anchor 1, onto which one
Spreizhülse 7 axial verschiebbar aufgesetzt ist. Auf dem Grund 8 der Bohrung für das Innengewinde 5 des Ankergrundteils 4 sitzt ein hülsenartiges Stauchelement 9 aus Kunststoff auf. Sein Außendurchmesser ist so gewählt, das es mit leichtem Presssitz gefügt und hierdurch verliersicher im Ankergrundteil 4 angeordnet ist.Expansion sleeve 7 is placed axially displaceable. On the bottom 8 of the bore for the internal thread 5 of the anchor base part 4 is a sleeve-like compression element 9 made of plastic. Its outer diameter is chosen so that it is joined with a slight press fit and is thereby arranged captively in the anchor base part 4.
Vor dem Einbringen des Spreizankers 1 in das Bohrloch 10 des Untergrunds 3 wird die Schraube 11 mit der Unterlegscheibe 12 soweit in das Innengewinde 5 des Ankergrundteils 4 eingeschraubt, bis das einführseitige Ende 13 auf dem Stauchelement 9 aufsitzt. In diesem Zustand wird der Spreizanker 1 soweit in das Bohrloch 10 eingeschoben, bis die Unterlegscheibe 12 und der Schraubenkopf 14 auf dem zu befestigenden Bauteil 2 aufsitzen. Im vorliegenden Fall ragt ein Teil des Ankergrundteils 4 in die Durchgangsbohrung 15 des zu befestigenden Bauteils 2. Hierdurch wirkt das Ankergrundteil 4 gleichzeitig zentrierend auf das Bauteil 2 und nimmt ggf. Querkräfte auf. Sollte dies nicht gewünscht sein, muss einfach nur eine entsprechend längere Schraube gewählt werden.Before the expansion anchor 1 is introduced into the borehole 10 of the base 3, the screw 11 with the washer 12 is screwed into the internal thread 5 of the anchor base part 4 until the end 13 on the insertion side is seated on the compression element 9. In this state, the expansion anchor 1 is inserted into the borehole 10 until the washer 12 and the screw head 14 rest on the component 2 to be fastened. In the present case, part of the anchor base part 4 protrudes into the through hole 15 of the component 2 to be fastened. As a result, the anchor base part 4 simultaneously acts on the component 2 in a centering manner and possibly absorbs transverse forces. If this is not desired, simply choose a correspondingly longer screw.
Zum Verspreizen des Spreizankers 1 wird die Schraube 11 angezogen. Durch denTo spread the expansion anchor 1, the screw 11 is tightened. By the
Kontakt der Spreizhülse 7 mit der Bohrlochinnenwand 16 und dem Spreizabschnitt 6 desContact of the expansion sleeve 7 with the borehole inner wall 16 and the expansion section 6 of the
Ankergrundteils 4 ist dieses drehgesichert. Damit wird das Ankergrundteil 4 entgegen der Einbringrichtung des Spreizankers 1 gezogen, während die Spreizhülse 7 axial auf dem Spreizabschnitt gleitet und hierdurch spreizend den Spreizanker 1 verankert. Gleichzeitig wird das Stauchelement 9 axial gestaucht und radial nach innen verdrängt. Dabei sind Material und Geometrie des Stauchelements 9 so aufeinander abgestimmt, dass es zu einem sehr leichtem Stauchen kommt, zumindest entlang des für das Spreizen der Spreizhülse 7 notwendigen Einschraubweges der Schraube 11. The anchor base part 4 is secured against rotation. The anchor base part 4 is thus pulled against the direction of insertion of the expansion anchor 1, while the expansion sleeve 7 is axially open the expansion section slides and thereby anchors the expansion anchor 1. At the same time, the compression element 9 is compressed axially and displaced radially inwards. The material and geometry of the compression element 9 are matched to one another in such a way that a very slight compression occurs, at least along the screwing-in path of the screw 11 necessary for the expansion of the expansion sleeve 7.
